Cottonwood, AZ: the heat pump payback math
Cottonwood clears a genuine payback here, inside a reasonable stretch of years. Against a like-for-like gas furnace and AC swap, going electric costs $1,000 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $333 saved annually, for a payback of roughly 3 years. That's a real payback, built from Cottonwood's own climate and utility rates, not a national guess.
Why Cottonwood's climate drives this number
Cottonwood has a mild winter by US standards — 2941 heating degree days a year against a 65°F base — and summers are hot enough that cooling matters as much as heating, at 2080 cooling degree days. 28.4°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 21.2°F on file. Worked through the model, that's a seasonal COP of 3.05 on the standard unit fit for this climate. A standard ducted system is enough here; Cottonwood's design temperature doesn't justify the cold-climate premium. These numbers come from SEDONA AIRPORT, the closest NOAA station, 13.3 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,442 kWh a year to keep it warm, plus cooling, for a combined electric bill near $655 a year. That compares with roughly 31 Mcf a year of gas at Cottonwood's 18.58 per-Mcf rate — about $988 a year — against a local electricity rate of 15.55¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 33.1 years, leaving the 15-year total $3,992 ahead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Cottonwood — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $922 a year comes back this way, enough that the 6-year payback clears the $5,500 premium comfortably within the equipment's life.
Cottonwood against the rest of the country
Cottonwood lands at position 1948 out of 3206 cities on heating severity (coldest is 1), and 2660 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
